摘要
借助棒状薄层色谱 (TLC)、核磁共振 (1H- NMR)以及凝胶渗透色谱 (GPC)分析技术 ,对石家庄催化裂化油浆与兖州煤、依兰煤、先锋煤以及汾西煤共处理重质产物的组成、结构和分子量进行了研究 .结果表明 :各种煤与 CCSO共处理的重质产物具有类似的族组成 ,芳香份含量显著增加 .共处理重质产物的分子量大都高于假定没有相互作用时煤和 CCSO单独处理的算术加和计算值 .重质产物的结构特征与煤的性质相关 .
Compositions and properties of heavy toluene soluble fractions (HTSF) from coprocessing coals of Yanzhou (YZc), Fenxi (FXc), Yilan (YLc), and Xianfeng coals (XFc) with Shijiazhuang catalytic slurry oil (CCSO) were studied using the thin layer chromatography (TLC), nuclear magnetic resonance (NMR) and gel permeation chromatorgraphy (GPC). The effects of CCSO addition on TLC compositions, structural parameters and molecular weight of HTSF were also investigated. The results show that the HTSFs from coprocessing of CCSO and different coals have a similar group composition. The content of aromatics increases significantly, and the asphaltenes decreases greatly after coprocessing. The molecular weight of HTSF from coprocessing is higher than the calculated value from coal and CCSO hydrogenation on the same conditions. The structure of HTSF is related to the properties of raw coal.
